Build: Enable std::vector ASAN annotation in libstdc++
...
By defining _GLIBCXX_SANITIZE_VECTOR when ASAN is enabled `std::vector` operations
will be annotated so ASAN can detect invalid accesses.
See https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_macros.html

Build: Disable Wstringop-truncation in GCC ASAN builds
...
These two options don't work well together and lead to false positives.

Build: Enable VLA warnings
...
VLAs (variable-length arrays) are a C99 feature and were never standardised for C++.
There are better alternatives in C++ (mainly std::vector). Enable the warnings
so no new ones can be introduced.

Build: Add CMake option to enable Werror

With -DENABLE_WERROR the -Werror flag will be passed to the compiler failing the build if a warning is emitted.

xenial has cmake 3.5.1. VERSION_LESS_EQUAL was introduced in 3.7. So lets use VERSION_LESS,11 instead

Build/GCC: Suppress -Wclobbered warnings on older compilers

There were a high number of false positives with old compilers. Suppress these warnings on them.

Build: Enable -Wconditionally-supported on GCC
...
We want to have warnings if we use some implementation-specific features of GCC
to be able to keep compatibility with clang.

build: Enable Wextra with some exceptions
...
-Wno-cast-function-type:
Signal handler code relies on this.
-Wno-type-limits:
Some of the color space conversion code in zm_image throws this warning. To not break anything let's ignore this warning for the time being.
Note that clang enables -Woverloaded-virtual with -Wextra. To not flood the GCC build log with warnings let's not enable this at the moment.
This will be done in a second step, when the currently throwing code will be cleaned up.
